CURRENT MOTOR.

Application sied may 21,

ToaZZ whom t may' 'concern 1 Be it known that I, SADAMA ORIOKA, a.citizen of the United States, residingV at Honolulu, YTerritory ofHawaii, have invented certain new and usefuliImp-rovements ina CurrentMotor, ofwhioh the following is a speciiication. j l

vrlhe present invention relates to a current motor adapted to be placedin a swift :running stream of water so that .power may be generated forthe operation of a dynamo. Theinvention may'beused so that its power maybe `converted in other ways as desired.

The principal object of the invention is to provide a motor having asimple and eilicient structure which will be reliable and capable ofbeing constructed at a relatively low cost.

Another object ofthe invention is to provide a motor of this naturewhich may be assembled easily and which may be moved to a' position' atwhich it will not operate when desired.

With the above' and numerous other objects in view las will appear asthe description progresses the invention resides in certain novelfeatures of construction and in the combination and arrangement of partsas will be hereinaftermore 4fully described and claimed.

In the drawingp Y Figure 1 is atop plan View of the device embodying theinvention, and

Figure 2 is an elevation thereof. Y Referring to the drawing in detailit will be seen that the letter A indicates a stream of water flowing inthe direction ofthe a1'- row. a plurality of brackets are suitablymounted on the bank of the stream and are arranged in two verticallyaligned series. In one series of brackets 1 there is rotatably supporteda post 2 and in the other series of brackets 3 there is rotatablysupported a post 4. The posts 2 and 4 are of similar structure and arepreferably constructed with heads 5 at their upper ends which bear onthe upper brackets 1 and 3 supper-timy the posts in proper positions.These posts may be thus readily withdrawn from the brackets whendesired. An arm 6 is detachably fixed to the post 2 and a similar arm 7is detachably mounted on the post 4. These arms 6 and 7 normally projectout into the stream and are slightly curved. A plurality of stay ropes 8are attached to these arms so that they may be held out into -21 and22.Thevsection 21 1923. Serial No. 640,455.

the stream vin a manner which will be more clearly evident as thedescription progresses. The motor proper includes a chain 9 whichistrained over sprockets 10 and 11. The splrocketlO is constructed witha shaft 12 journaled inthe yoke 13 which is connected tothe end of thearm 6 by links 14. The sprocket 11 Vis mounted Aon a shaft 15 journaledin yoke ldwhich is attached to the arm7 by links 17. The shaft 15terminates beyond the yoke 16 in an eye 18. The chain 9 is providediwitha plurality of paddles 19. These paddles are hingedly connected to thechain so as to swin 1n a 90 are whereby they may be disposedperpendicularly to the chain or parallel thereto. When the paddles `19are disposed parallelwith the cham the all extend in the same directionprovide of course, that the chain is extended flat. In actual practicethe paddles below the plane ofthe shafts 12 and 15 are disposed parallelwith the chain while those above the plane of these shafts are disposedperpendicularly to the chain. It will vthus be seen that the water owingin the direction of the arrow will cause movement of the chain since itwill engage the paddles, bring them to their perpendicular Aposition inrelation to the chain therebytending to resist the low of water. As apaddle' approaches the yoke 13 it will be pivoted to its parallelposition with the chain so as to afford aminimum amount of resistanceasit is moving toward sprocket 11.

. so `A shaft indicated generally `at 20 includes a pair-l oftelescopically associated sections telescopes into the section-22 and isrotatable therewith in any suitable manner. The section 22 is journaled`in a bracket 23 supported by an arm 24 which proj ects from the post 4being detachably engaged therewith by a bolt 25. Thesection 22 of theshaft 2O terminates adjacent the shore in a beveled gear 26 which mesheswith ya beveled gear 27 mounted on the lower end of a shaft 28 which isjournaled in bracket 29 suitably mounted at the bank or shore. Thisshaft 28 terminates at its upper end in a beveled gear 30. A collar 31is disposed immediately below the beveled A gear 30 so as to rest on ajournal bracket 32 supported by arm 33 projecting from one of thestandards 34. These standards 34 are located on a ports a dynamo 36operable through a gear 37. A shaft 38 is journaled in the ends of base35 which supldisposed be also noted that if the motor is moved 'towardand away the standards 34 Vand is provided at oneend with a beveled gear39 meshing with the beveled gear 30 and Vat its other end in a gear 40meshing with the gear 37.

It will thus be seen that when the motor is operated by the stream ofwater, the shaft 20 will be ro-tated causing rotation of shaft 38through beveled gears 26 and 27. The rotation .of this shaft 38 operatesthe dynamo through the ntermediacy of gears 30 and 39, shaft 38, andgears 40 and 37. If it is desired to stop the motor it is only necessaryto rotate the arms 6 and 7 ina clockwise direction, as shown in Figure1, since this Vwill cause the rotation of the varm 24 and separate thebeveled vgear 26 on shaft 20 from beveled gear 27. Furthermore if it isdesired to bring the motor close to vshore so that it may be cleaned orrepaired while actually in the water these arms may be still fartherrotated since the more they are rotated toward `the shore the closerwill be the motor to .the shore. It will toward the shore the section 21of shaft 20 will move out of section 22 and that this telescoping shaftor any similar extensible shaft is desirable and necessary to theeflicient operation and care ofthe mechanism. It is also desirable, ofcourse, to bring the motor close to shore'when for any reason it is ltobe disassembled.

The particular structure and the. arrangement and combination of theelements thereo f which I have f, disclosed with a certain degreeofparticularity may be variously arranged and constructed without`departing from Vthe scope or spirit of the invention as 'hereinafterclaimed.

Having thus described my invention what I claim as -new is 1. Incombination, a water propelled motor, an eXtensible shaft operable bysaid motor, means for holding the motor out in a stream of water, y ableso that Said motor may be moved from the shore of the stream, therebyextending or contracting the length of said extensible shaft.

2. In combination, apair of spaced hinged arms, a current motorsupported between .terminating in an eye,

said means being actuatand by said arms, means for holding said armsprojected ont into a stream of water and so as to rotate said armstoward the bank of said stream whereby the motor may be moved close tosaid bank, and an eXtensible shaft operable by said motor for operatinga mechanism on the shore of said stream.

3. In combination, a pair of arms adapted to be hingedly mounted on thebank of a stream of water, a current motor supported between and by saidarms in said stream of water, a. shaft operable by said current motor, asecond shaft of extensible type pivoted to the first shaft.

4. In combination, a pair ofarms adapted to be hinged to a bank ofastream of water,

means for holding said arms out into said stream of water and movingthem toward said bank, a pair of yokes vone attached to the end ofeacharm, a pair of sprockets one journaled in each yoke, va chaintrained over certain sprockets, paddles hinged .toV said chain so as tomove in a 90 arc, and means for. transferring the power generated bysaid chain to a mechanism on the bank.

5. In combination, a pair of arms adapted to be hingedto a bank of astream of water, means for holding said arms out into said stream ofwater andmoving them toward said bank, a pair of yokes one attached tothe end of each arm, a pair of sprockets one journaled in each yoke, achain trained over certain sprockets, paddles hinged to said .chain soas to move in a 90 arc, ashaft extending from one of` said sprockets anda second shaft 1ncluding telescoping sections one of which terminates inan eye engaged with the eye of the first shaft, and a bracket in whichsaid second shaft is jonrnaled whereby the sections of the second sha-ftmay contract when the arms are moved toward the bank of the stream.

In testimony whereof I afx my signature `in presence of two witnesses.
